code 21 please help.....
hey guys i have a b16a swapped crx. well i had a pr3 ecu that came with the swap installed for awhile. so i decided to buy a real spoon programmed pwo ecu. the car runs great with it. but i just got a check engine light. so i checked the ecu and i got this code. it has like 2 long flashes and a quick 1. so im supposing this is a code 21. the car still runs fine but has this code. now what should i do. what does this code mean?
thanx in advance
